Abstract (en)
[origin: EP1489053A1] A glass ceramics having a chemical composition of aRO.bNb2O5.cSiO2.dB2O3.eTeO2.fX (where R represents Ba and/or Sr, X represents one or more oxide selected from the group consisting of TiO2, ZrO2, P2O5 and ZnO, a>b≥0.05, 0.60≥c≥0, 0.70≥d≥0, 0.70≥e≥0, c+d+e≥0.175, a+b+c+d+e=1.0 and 0.10≥f>0). The ratio dielectric constant at 1 kHz epsilon 1 to dielectric constant at 100 kHz epsilon 100 ( epsilon 1/ epsilon 100) is 10 or more. <IMAGE>
